In any city there are a lot of squares. But one square, as a rule, the historical center of the city, is the most beloved among both city dwellers and tourists. In Prague, this is the Old Town Square (or Staroměstské náměstí).
In its importance and attendance, the Old Town Square is not inferior to the fortress of Prague Castle or the famous Charles Bridge.
It is most convenient to get there by metro. You need to quit at any of the stations: Mustek, Namnesti or Staromestsk. Or on 17.18 trams to the stop of Staroměstská.
A few steps - and you are in the square.
